All 42 state parks are offering free admission Thursday to veterans in honor of Veterans Day.

“In honor of their dedication to service, country and freedom, Colorado State Parks is pleased to offer veterans free entrance to state parks,” said Gary Butterworth, a state parks board member from Colorado Springs. “We owe this nation’s military men and women a debt of gratitude that can never be fully repaid.”

Well said. Vets must show some sort of military or Veterans Affairs ID or something showing service time to get the freebie admission.

That U.S. Marine Corps tattoo you got in San Diego probably won’t work, but it’s worth a try.

WHAT: Free admission to all vets to Colorado state parks.

WHERE: There are 42 state parks, including Highline, James M. Robb/Colorado River, Vega and Ridgway state parks, all within marching distance.
